Hinge dampening device for granulation bowl lid
a technology of granulation bowl and dampener, which is applied in the direction of door/window fittings, pin hinges, etc., can solve the problems of increasing the cost of granulation, increasing the risk of operator injury, and increasing the difficulty of controlling the opening and closing movement of the lid, so as to increase or decrease the axial compression, the effect of adjusting and reducing the axial compression

Benefits of technology
The invention is a hinge which allows a lid to be opened and closed with controlled resistance. It includes two fixed supports on a bowl and a collar on the lid that holds a hinge pin. Belleville washers are placed on the hinge pin, and a jam nut and locking acorn nut are threaded onto the hinge pin to adjust the resistance. This allows for smooth opening and closing of the lid.
Problems solved by technology
As the lid weight increases, control of the opening and closing movement of the lid becomes more difficult.
Accidental slamming of the lid creates a risk of injury to the operator.
However, these structures add more cost to the granulator.

Embodiment Construction
[0018]A granulation processor is generally designated by the reference number 10 in the drawings. The processor 10 includes a bowl 12 with a lid 14 movable between a closed position covering the top of the bowl 12 and an open position allowing access to the interior of the bowl 12.
[0019]The hinge dampening device is generally designated by the reference number 16. The dampening device 16 includes first and second hinge supports 18, 20 fixed to the bowl 12, using bolts or screws 21 or other securement means, in a spaced apart relationship. A pin 22 has a first end 24 extending into the first support 18 and fixed to the support 18 by one or more bolts 25 or other fasteners, so as to prevent rotation of the pin 22. The second end 26 of the pin extends through the second support 20. The pin 22 extends through a collar 28 of the lid 14 which resides between the hinge supports 18, 20. A pair of flanged bushings 30 are press fit into the opposite ends of the collar 28 before the pin 22 is ...

Abstract
A hinge dampening device is provided for a granulation processor having a bowl and a lid. A dampening device includes first and second spaced apart hinge supports fixed to the bowl and a pin extending through the lid collar residing between the hinge supports. The first end of the pin is fixed to the first hinge support, and a second end of the pin extends through the second hinge support. An adjustable compressive force is applied axially to the hinge supports and lid collar to create frictional resistance to rotation of the lid. The rotational resistance provides controlled opening and closing of the lid.
Description
FIELD OF THE INVENTION[0001]The invention relates to the field of granulation processors and particularly to a lid hinge dampener for a granulation bowl.BACKGROUND OF THE INVENTION[0002]Granulation mixing systems exist in several forms. One form is a bottom drive, high sheer, wet granulation mixer having a bowl with rotary mixing blades and a lid which removably covers the bowls. The bowls and lids come in various sizes, with the lids of bigger bowls being substantially heavier than for smaller bowls. As the lid weight increases, control of the opening and closing movement of the lid becomes more difficult. Accidental slamming of the lid creates a risk of injury to the operator. Some prior art granulation bowls includes a hydraulic or pneumatic cylinder to control opening and closing of the lid. Other prior art granulation bowls include a counter weight on the lid to assist in controlled opening and closing. However, these structures add more cost to the granulator.[0003]Therefore, ...
